摘要

Heats of formation and geometries of benzocyclopropene, cyclopropa [b] naphthalene, bicyclo [4.1. 0] hepta-2, 4, 7-triene, and benzannelated derivatives have been calculated with a combined force field-SCF program. The bicycloheptatrienes are stabilized relative to the isomeric arylcarbenes by benzannelation, and destabilized by loss of aromaticity and/or increased strain. 1-Naphthylcarbene, 2-naphthylcarbene, 9-phenanthrylcarbene and 9- ...
